WIRE-WINDING MACHINE.

Application filed September 5, 1911. Serial No. 647,588.

To all whom it may concern:

Be it known that I, ALBERT LINDSAY EASTHAM, a citizen of the United States, residing at Beaumont, in the county of .J efferson and State of Texas, have invented certain new and useful Improvements in Wire- Winding Machines; and I dd declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to an improved machine for use in winding wire around perforated pipes in making well screens or strainers, such as are used'in oil wells or Artesian water wells. These screens or strainers serve to exclude sand, or other foreign materials, from the liquids to flow or to be pumped from the wells, and it is therefore necessary that the convolutions of wire should be laid on the perforated pipes with exactness. The perforated pipes which are used in the formation of these screens or strainers are usually of considerable length, and are also usually of wrought steel,

As they are always more or less crooked or uneven they will wabble more or less as they are rotated in the lathe for the winding operation, and it is therefore necessarythat the wire-presenting and holding device should be of such a character that it may move freely, in different planes, so that it may accommodate itself to the irregularities or wabbling movements of the crooked or uneven pipes.

In carrying the present invention into effect the wire guiding device comprises certain guiding rollers or devices which are carried by pivoted parts so that the guiding devices will be free to vibrate or oscillate in different planes, and thus accommodate themselves to the irregularities in the pipes.

In the accompanying drawings Figure 1 is a side view of a preferred form of the present invention, with the perforated pipe being wound represented in cross section. Fig. 2 is a cross section of the improved wire winding device on line 2-2, looking in the Patented Aug. 20, 1912. I

direction of the arrows adjacent to said line.

Referring to the drawings, 12 denotes standards which are to be secured to the lathe carriage which will, in practice, be fed along, to s ace the turns or convolutions of the wire, y the usual lathe feed screw. Bolted to the standards 12, in such a manner that it may be adjusted vertically on said standards, is a bar or plate 13 to which is rigidly secured an offset plate 14 carrying a series of wire guiding tension rollers 15, 16. The lower rollers 15 are preferably grooved, and the upper rollers 16 plain.

Pivotally secured to the bar or plate 13, by means of a fulcrum stud 17, is an oscillating block or plate 18 to the rear side of which, as the parts are represented in Fig. 1, 1s adjustably attached an arm or bar 19 having a curved lower end which is provided with a curved slot 20. On the said curved lower end of the arm or bar 19 is mounted a roller 21 which may be adjusted to different positions on the said arm, by virtue of the said curved slot 20; and the said arm or bar 19 may be adjusted to different vertical positions relative to the said block or plate 18 b virtue of the slot 22 with which the straight upper part of said arm or bar 19 is provided. Also the slot 23' in the plate or block 18 permits the upper end of said arm or bar 19 to be adjusted lengthwise of said slot; and furthermore permits it to be tilted to various positions, for a purpose which will be hereinafter explained.

Pivotally mounted on the plate or block 18, by means of the stud 24, is an oscillation plate or block 25 carrying at its free end a guiding roller 26; and mounted on the lower part of the said oscillating plate or block 25 are two wire guiding ro lers 27 and 28. The roller 27 is preferably provided with a wire guiding groove in its periphery, as more clearly shown in Fig. 2, and the roller 28 is or may be a plain roller.

From the foregoing it will be understood that the plate or block 18, with which is connected the steadying roller 21, will be free to oscillate or swing on its fulcrum stud plate or block 18, will be free to vlbrate vertically or up and down, these different movements of the parts permitting the wire guiding devices to accommodate themselves to the irregularities of a rotating perforated pipe, as 29, on which the wire is being wound in closely spaced convolutions. I

In the operation of this wire winding machine the wire 30 passes through a tension block 31 to the guiding tension rollers 15 and 16, and thence to the guiding rollers 27, I

28 and 26, which present it in proper position to the rotating pipe 29 and as the wire winding device is fed along by the'usual feed screw of the lathe the wire will be laid upon the perforated p pe in closely spaced convolutions, as hereinbefore stated.

In the use of the machine for winding "pipes of different sizes 011;) diameters certain adjustments of the parts will be necessary, in order to accommodate such different sized pipes. This is provided for by the adjustable arm or bar 19 and the adjustable mounting of the roller 21 therein, as the said roller may be moved to different vertical positions on the lower portion of said arm or bar by virtue of the curved slot 20 in the lower part thereof; and the said arm or bar may be adjusted to different vertical positions, by virtue of the slot 22 in the upper part thereof; or, the said arm or bar may be tilted to various positions, as hereinbefore indicated, by virtue of the said slot 22- therein and the slot; 23 in the 'block or plate 18.

Having thus described my invention I claim and desire to secure by Letters Patent:
